I'm trying to do a Garmin GMC 710 project at home using SimVim with Arduino Mega 2560.
My Encoders and Switches are working perfect but I have some issues with led announciators.
You can see my device and simvim configurator page in the attachments.
My issues are :
When I press the HDG button ; HDG led turns on but also ALT led is turns on on my device but not on the dashboard on the screen. If I press again the HDG button its led turns off both on my device and on the screen. But ALT led on my device remains on. To put it off if I press the ALT button little blink happens and remains on. Only if I press FD button all leds go off. Why I can't sync my device with simulator screen ?
Other issue is : If I press the APR button, both APR & NAV led turns on and again ALT goes on. But on the simulator screen again ALT led is of. I press APR leds goes of, I press NAV leds goes of but ALT led remains on on my device. Same with other issue If I press ALT button on the screen LED goes of but on my device it remain on all the time until if I press the FD button all leds goes off.
Does anybody can help me ?
